IMPROVEMENT IN WATER-WHEELS.

' 'Jl'he Schedule referred to in these Letters Patent and making part ofthe same.

To all whom 'it may concern.;

Beit known that I, SAMUEL MARTIN, of the city 'and county of York, andState of Pennsylvania, have invented a newand improved Water-Wheel; andI do hereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the accompanying drawings'rnaking apart of thisspecification, in which- Figure lis a vertical central section througlnthe wheel, and

Figure 2 is a plan view Vof the curb, gates, and curved plates. v

This invention consists of certainimprovements .in turbine water-wheels,tending to increase their efficiency, as will hereinafter more f'ullyappear.

In the drawingsi The wheel'is shown to consist of au upper disk, a, alower disk, a', the lower being of somewhat greater diameter than` theupper, an intermediate parallel i ring, a", of the same diameteras thelower disk, the

upper and lower. disks being connected by a web, b. Projecting radiallyfrom the web b are vertical buckets bI the upper ends of which areplaced beneath the disk a, 4while their lower ends are even with theunder side of the ring c, which ring serres to support their lower partsbetween .itself and the web b.

The ring rests on curved buckets c, which 'themselves rest on the lowerdisk.

The curved buckets extend inward to the inner side of' the ring a", andoutward nearly to its outer side.

'lbewater acts directly ou the 4buckets b', then falls upon the lowerdisk, and is, by't-lic centrifugal action ot' the wheel, swept againstthe inner sides of the. buckets c,'and out'of the', wheel between theends of said buckets. lt thus'imparts a. reactionary force 'to ithecurved bucket-sl in addition lto its direct action upon the bucketsb'. y y

To eachcurved buckets there is secured, by a set- -screw passingthrough' a slot lin the bucket, a'plate, c',

of the same shape andsze,'whose couvexity ts accurately the concavty ofthe bucket, and which may be 4slid outward, according to the length ofthe slot iu -the bucket, and thus diminish the size of the open# ingsbetween the buckets, so is to prevent waste of' water.

In iig. 2 are seen the gates d, each by itself, and attached to a radialarm, d', projecting from a central hub, di.

The gates are arranged in pairs, the two of cach pairbeing exact-lyopposite each other, at dili'ereut sides of the curb, and all the gatesmoving at the same time.

This'arrangement places thegates in equilibrium as to the pressure otthe water, rendering it 'easy to open enclose them.

The end of each gate that enters the opening in the curb is providedwith a curved vertical plate, e, set at an angle across such end andextending inward far enough to conduct the water past the Wal] of thecurb.

Such plates form, with the 'plates e of the curb, gnideways that conductthe water 4to the wheel tangentially.

Having thus described my invention,

What I claim vas new, and desire to secure by Let ters Patent, is, 1.The combination of the vertical buckets b' with the curved bucketsc,',inthe manner described and for the purpose of enabling the waterboth .to act directl y and to react upon the wheel.

. 2. In combination with the curved buckets c, the sliding adjustableplates c', in the manner and for the purpose described.

' 3. rlhe 'detached gates d when so combined with the revolving frame ild as to be all in equilibrio, in the manner and for the'purpose setforth.

,4. The gates' d combined with .the curved plates e, for the purpose offorming a perfect guideway, subst-antially as specified.

To the above specification ot my invention I have signed myA hand this30th day of November, 1869.

S. MARTIN.
